Kubudirira kutsva munyika yemagineti kuri kuvimbisa kufambira mberi kwekuchinja kwemitambo mumaindasitiri akasiyana. Magineti epasi asingawanzo, kunyanya neodymium magineti, ari kuwana kutariswa kwakawanda nguva pfupi yadarika nekuda kwemabhenefiti avanopa pamusoro pemagineti echinyakare.
Neodymium magineti, anonziwo NdFeB magineti, imhando yeasingawanzo pasi magineti anozivikanwa nekuda kwesimba rawo rakasiyana uye magineti zvimiro. Izvo zvakagadzirwa neodymium, iron, uye boron, uye zvine simba remagineti rakasimba zvakapetwa ka25 pane iro remagineti echinyakare.
Kumwe kushandiswa kukuru kwemagineti neodymium kuri muindasitiri yezvokurapa, kwaanoshandiswa mumichina yemagnetic resonance imaging (MRI) nekuda kwekugona kwavo kugadzira magineti akasimba. Iyi tekinoroji yakasandura nzira iyo vanachiremba vanoongorora nekurapa varwere, vachipa nzira dzakanyatsojeka uye dzisingapindire dzinovandudza mhedzisiro yevarwere.
Kumwe kushandiswa kukuru kweneodymium magineti kuri muindasitiri yemotokari. Aya magineti anoshandiswa mumamota emagetsi, kunyanya mumotokari dzakasanganiswa uye dzemagetsi. Kusimba uye kushanda zvakanaka kweneodymium magineti inobvumira kukwidziridzwa kuri nani uye kureba kwekutyaira kwemotokari idzi, izvo zvakakosha sezvo vanhu vazhinji vachitora mota dzakachena dzemagetsi.
Mamwe maindasitiri ari kutora mukana wezvakanakira neodymium magineti anosanganisira zvemagetsi zvevatengi, aerospace, uye kugadzirwa kwesimba. Mune zvemagetsi, neodymium magineti anoshandiswa mumahedhifoni, mutauri, uye hard disk drive nekuda kwehukuru hwayo hwecompact uye simba remagineti. Mumuchadenga, magineti aya anoshandiswa mumasensa uye avionics masisitimu, uko huremu uye hwakavimbika tekinoroji yakakosha. Mukugadzira simba, neodymium magineti anoshandiswa mumhepo turbines, ayo anogadzira simba rakachena nemutengo wakaderera pane yechinyakare fossil mafuta.
Pasinei nemabhenefiti avo, neodymium magineti haasi asina matambudziko. Chimwe chinonetsa mutengo wavo wakakwira, unokonzerwa nekushaikwa kwezvinhu zvinoshandiswa mukugadzira kwavo. Pamusoro pezvo, magineti aya ane brittle uye anogona kukuvara nyore nyore kana asina kubatwa nemazvo. Nekudaro, makambani ari kuisa mari mukutsvagisa kuti akunde matambudziko aya uye kutsvaga nzira dzekuita neodymium magineti atonyanya kuwanikwa uye mushandisi-ane hushamwari.
Pakazere, kufambira mberi kwazvino mumagineti epasi asingawanzo, kunyanya magineti eodymium, zviitiko zvinonakidza zvine mukana wekushandura maindasitiri mazhinji. Kunyange kuchine matambudziko ekukunda, mabhenefiti eaya magineti anovaita nzira yakakosha yekuvandudza uye kufambira mberi mune ramangwana.
